Both front doors in my '02 325i make a "squeaking" sound while I'm driving. The passenger door is worse. It sounds like the windows are rubbing against the seals, but the sound doesn't diminish or go away if I push against the glass to try to stop it. Could it be something else? The noise goes away completely if I lower the windows.
I don't hear it when I have the radio up, but it's a little annoying when I want to go for a quiet drive. Should I take it in for repair, or is there a neat trick to fix it?
